The site is located at 164 Bostian Bridge Road, which is near Buffalo Shoals Road (State Road 1004) in Statesville, North Carolina (Figure 1). A site map is provided as Figure 2. Soil and groundwater impacts from former asphalt testing operations were previously identified at the site. The asphalt testing utilized trichloroethene (TCE), 1, 1, 1 -trichloroethane (1,1,1-TCA), and/or carbon tetrachloride (CTC). The approved CAP included excavation for source area soil and monitored natural attenuation (MNA) for groundwater impacts. Approximately 162 tons of impacted soils were removed from the source area in September 2001 as reported in H&H's Semi -Annual Monitoring and Soil Remediation Report dated February 19, 2002. Confirmation soil samples indicated that soils were adequately removed. Monitored natural attenuation, consisting of semi-annual or annual groundwater monitoring, was conducted at the site from 2002 until prior to the bioenhancement injection in December 2012. Because TCE concentrations remained more than two orders of magnitude above the groundwater standard, a stream is located near the plume, and there is no public water available in the area of the site, H&H recommended that the bioenhancement event be conducted in shallow groundwater where TCE concentrations were the highest. Bioenhancement improves subsurface conditions for more efficient natural attenuation by reductive dechlorination. On behalf of DOT, H&H prepared an Underground Injection Control (UIC) Permit Application dated August 24, 2012 to conduct a bioenhancement injection at the site. The injectant selected 1 hart hckman SAAAA-Master Proje BBC DOT-DOTtDOT-500s Contract'DOT-504 StatesvWe 661May 2015 Report\Sewi-Amoral GNAt Report.doc -- SMARTER ENVIRONMENTAL SOLUTIONS for the bioenhancement injection event was Emulsified Oil Substrate (EOS®). DENR issued the UIC permit on November 9, 2012. The bioenhancement injection activities were conducted in December 2012. The injection event included 36 temporary direct push technology (DPT) injection points and injecting the EOS® into the upper 20 ft of the saturated zone. The 36 temporary DPT injection wells were installed approximately 20 ft apart perpendicular to groundwater flow and approximately 35 ft apart parallel to groundwater flow within the target treatment area. The DPT temporary injection wells were advanced to depths ranging from approximately 27 ft to 42 ft below ground surface (bgs). The injection area and injection well locations are depicted on Figure 4. The EOS® concentrate was mixed with water prior to injection using an approximate mixing ratio of 1:6 (EOS® to water). For the project, a total of approximately 1,618 gallons of EOS® concentrate were mixed with approximately 10,666 gallons of potable water and injected into the subsurface. The quantity of EOS® was determined using EOS Remediation, LLC's EOS® Design Tool (Version 3.0) software. Approximately 323 to 508 gallons of diluted EOSO mixture were injected into each injection well. This post -injection semi-annual groundwater monitoring report includes a summary of post - injection groundwater monitoring between July 2014 and February 2015. 2 hart hickman &VILAA-Master Projects\NC DOT-DOTtDOT-500s Coatract%DOT-504 Statesville 66\ML ay 2015 Report\Semi-Auuual GNL1 Report.doc SMARTER ENVIRONMENTAL SOLUTIONS 2.0 Potential Receptor Survey Update A summary of area receptors is described below and was updated in November 2014. The next annual receptor survey update will be conducted in the second half of 2015. 2.1 Water Supply Wells The November 2014 receptor survey update was performed by reconnaissance within 1,500 ft of the former asphalt -testing laboratory and by contacting the local utility department to confirm that no municipal wells are in the area. During the November 2014 receptor update, no additional water supply wells were identified within 1,500 ft of the site. A total of 18 water supply wells (active, inactive, or abandoned) are located within a 1,500-ft radius of the former asphalt -testing laboratory. The locations of the water supply wells are indicated on Figure 3, and a summary of water supply well information is provided in Table 1. Of the 18 water supply wells, four wells are located on -site and are designated as WSW -I, WSW-2, WSW-4, and WSW-4A. In accordance with the approved CAP, H&H abandoned water supply wells WSW-1 and WSW-2 in September 2001. Water supply wells WSW-4 (deeper) and WSW-4A (shallow) are located approximately 500 ft southeast and upgradient of the source area. WSW-4 serves the entire subject property and WSW-4A is inactive. Target volatile organic compounds (VOCs) have not been detected in WSW-4 including during the most recent sampling event in February 2015 (Table 2). No off -site water supply wells are located downgradient of the former asphalt -testing laboratory. Each of the 14 off -site water supply wells is located upgradient or cross -gradient of the former asphalt laboratory. The closest off -site water supply well (WSW-5) is situated cross -gradient of the site approximately 650 ft southwest of the former asphalt laboratory. One of the 14 off -site water supply wells (WSW-3) is located cross -gradient of the former asphalt -testing laboratory on the Dorothy Davis property (across an unnamed tributary of Third Creek and approximately 1,200 ft northeast of the former laboratory). WSW-3 was 3 hart hickman S:1AAA-Master Projects`NC DOT-DOTIDOT-500s Contract`DOT-504 Statesville 66Way 2015 Report\Semi-Amwl GWIvi Report.doc SMARTER ENVIRONMENTAL SOLunous sampled in September 1997 and again in October 1998. No target compounds were identified in either sample. Further, a deep saprolite monitoring well (DMW-8), located on the same side of the tributary as WSW-3, is not impacted. The lack of impacts in DMW-8 indicates that the tributary acts as an effective hydraulic barrier. Based on the distance from the former laboratory, the known extent of the contaminant plume, and topographic and hydraulic gradient considerations, the potential for site groundwater impacts to affect the off -site water supply wells is considered to be low. 2.2 Surface Water Two surface water bodies are located within a 0.25-mile radius of the subject site (Figures 1 and 3). An unnamed tributary to Third Creek is located approximately 400 ft north of the former laboratory and borders the northern property boundary. In addition, Third Creek is located approximately 600 ft west of the former laboratory and borders the western property boundary. Both of these surface water bodies appear to be discharge locations for site groundwater. In February 1999, surface water samples were collected from both the unnamed tributary and Third Creek at locations along the northern and western property boundaries of the site. In addition, H&H collected a surface water sample (labeled SS-2) in June 2015 from the unnamed tributary of Third Creek (Table 4 and Figure 2). The surface water sample was analyzed for purgeable halocarbons by EPA Method 6200B. Target compounds were not detected in the surface water sample. In addition, groundwater modeling conducted as part of the CAP indicates that target compounds will not be present in these surface waters above surface water quality standards in the future. Recent surface water sampling activities are discussed further in Section 3. 4 hart ` hickman SAAAA-Mmler Proje ONC DOT-DOT\DOT-500s Contra&-DOT-503 Statesville 66�May 2015 ReporttSeuri-Auuoal GVAI Report.doc SMARTER EWRONMENTAI SOLUTIONS I � 3.0 Groundwater/Surface Water Monitoring As outlined in the UIC permit, H&H conducted a pre -injection groundwater monitoring events on February 2 and 3, 2012 and December 7, 2012 to establish a baseline for comparison with post - injection monitoring data. Additionally, H&H performed quarterly post -injection monitoring events in February 2013, April 2013, June 2013, October 2013, January 2014, May 2014, July 2014, November 2014, and February 2015 to assess the performance of the implemented enhanced bioremediation remedy. The April 2013, October 2013, May 2014, and November 2014 quarterly sampling events were comprehensive events as outlined in the UIC permit application. The groundwater sampling procedures and monitoring results for the most recent monitoring event in February 2015 are discussed below. The locations of the monitoring and temporary injection wells are indicated on Figure 4, and monitoring well construction information is provided in Table 3. 3.1 Data Collection Procedures H&H sampled deeper saprolite monitoring wells DMW-1, DMW-2, DMW-6, DMW-8, DMW-9, DMW-10, and DMW-11 and bedrock monitoring well DMW-7. Additionally, bedrock monitoring well DMW-3, which could not be located during the November 2014 sampling event, was located with a metal detector and sampled. Samples from these wells were submitted for laboratory analysis of VOCs by Environmental Protection Agency (EPA) Method 6200B (reporting the EPA Method 601 list), nitrate, sulfate, sulfide, methane, ethane, ethee, Resource Conservation and Recovery Act (RCRA) metals (arsenic, barium, cadmium, chromium, lead, selenium, silver, and mercury), and total organic carbon (TOC). Field measurements were also collected from these wells and the unnamed tributaryof Third Creek for dissolved oxygen DO Yg ( ), oxidation-reduction potential (ORP), specific conductivity, ferrous iron, pH, and temperature. In addition, one surface water sample was collected from the unnamed tributary of Third Creek located north of the site for laboratory analysis of VOCs by EPA Method 6200B (reporting the EPA Method 601 list) on June 2, 2015. 5 hart hickman &NAAA-:-faster Proje tsWC DOT-DOTIDOT-500s ContraefDOT-504 Statesville 66tMay 2015 Report\Seni-Annual GR'Xf Report.doc SMARM EAMRONMENTAL SOLUTIONS The sampling event was conducted using the following procedures. After monitoring well water levels were gauged, DO concentrations were measured using a downhole probe. Following DO measurements and prior to collection of groundwater samples, the target wells were purged using dedicated disposable bailers until pH, temperature, and specific conductivity levels stabilized. If a well went dry during purging, the purging process was considered to be complete. Groundwater samples were collected with dedicated disposable bailers. Groundwater samples were submitted for laboratory analyses of VOCs using methods listed above. Pace Analytical Laboratories, Inc., a North Carolina -certified laboratory, conducted the laboratory analyses. Dedicated laboratory -supplied sample bottles were used for sample collection. A chain -of -custody record was completed for samples collected and included sample description, date collected, time collected, matrix, sample container information, and analyses required. The chain -of -custody was signed by H&H and placed along with the samples in a chilled cooler for hand delivery to the laboratory by H&H. Copies of the laboratory analytical data sheets and chain -of -custody records are provided in Appendix A. 3.2 Groundwater Levels and Flow Direction Water levels in site monitoring wells were gauged using an electronic water level meter on February 3, 2015 (Table 3). The estimated saprolite potentiometric map constructed from the February 2015 groundwater elevation data is presented as Figure 5. The potentiometric map was constructed using both shallow and deeper saprolite water levels. Consistent with previous data, groundwater flow in the saprolite aquifer is generally to the northwest in the direction of Third Creek and its tributary. The shallow groundwater has a calculated horizontal hydraulic gradient of approximately 0.04 ft/ft. 3.3 Surface Water Measurements and Analytical Data As required in the UIC permit, quarterly surface water measurements were collected from the unnamed tributary of Third Creek at locations upstream (SS-1) and downstream (SS-2) of the injection area to determine if the bioenhancement injection activities are adversely impacting the - 6 hart 0-S. hickman SAAAA-Master ProjectsV\C DOT-DOT\DOT-500s ContracPDOT-504 Statesville GG\May 2015 Report\Senti-Anmwl GNbi Report.doc SMARTER EM+iAONM€Mnl SOLUTIOt75 creek. The locations of SS-1 and SS-2 are depicted on Figure 2. Based on similar data between the two locations during each sampling event, the bioenhancment injection has not adversely impacted the tributary (Table 8). H&H will continue to collect surface water field measurements at locations upstream and downstream of the injection area on a quarterly basis. Should field measurements indicate impacts to the tributary, surface water samples would be collected from the tributary and analyzed for various parameters as outlined in the UIC permit. As outlined in the UIC permit application, a surface water sample was collected from the unnamed tributary of Third Creek at a location (SS-2) downgradient of the injection area on June 2, 2015. The sample was collected by lowering a bailer into the flowing stream. No VOCs were detected in the surface water sample (Table 4). 3.4 Groundwater Analytical Data Deeper Saprolite Analytical results from the February 2015 sampling event indicate groundwater impacts above groundwater standards in deeper saprolite monitoring wells DMW-6 and DMW-11 (Table 5 and Figure 6). TCE and 1,1-dichloroethane were the only two compounds detected above groundwater standards. The most elevated concentrations were detected in DMW-6. TCE was detected in monitoring well DMW-6 at a concentration of 41.8 µg/l, which is above the groundwater standard for TCE of 3 1. 1,1-DCA was detected in monitoring g well DMW-6 at a concentration of 42.3 µg/l, which is above the groundwater standard for of 6 µgll Consistent with previous sampling events, target compounds were not detected in deeper saprolite well DMW-8. Monitoring well DMW-8 is situated on the northern side of the unnamed tributary of Third Creek. The absence of groundwater impacts in DMW-8 indicates that the tributary is acting as an effective hydraulic barrier. hart hickman SAAAA-Master Projects`,NC DOT-DOT\DOT-500s Contract\DOT-504 Statesville 66\May 2015 Reporf Senti-Auuuat GWNI Report,doc SMARTER EWRtONMENTAt SOLUTIONS Bedrock In February 2015, target compounds were not detected above laboratory reporting limits in bedrock wells DMW-3 and DMW-7 (Table 6 and Figure 7), or in the on -site water supply well WSW4 (Table 2). Additionally, target compounds were not detected above laboratory reporting limits in bedrock well DMW-4 that was last sampled in November 2014. Bedrock well DMW-7 is located adjacent to deep saprolite well DMW-6, which is the monitoring well with the highest target compound concentrations. Although only approximately 25 ft separates the DMW-6 and DMW-7 well screens, the concentrations decrease with depth to non -detectable levels in DMW-7. Concentration Trends TCE is the most widespread target VOC detected above standards. Post -injection February 2015 data indicate that TCE levels have decreased from 68.5 µg/1 to 41.8 µg/1 in DMW-6, 3.3 µg/1 to 3 µg/l .in DMW-9, and 10.8 µg/1 to 7 µg/1 in DMW-11 since the injection in 2012. These trends indicate that the EOS® injection has resulted in enhanced bioremediation within portions of the groundwater plume area. Concentration trends will continue to be evaluated n t d dun future g p g sampling events. Concentrations of key VOCs in saprolite and bedrock groundwater are depicted on Figures 6 and 7. A graph showing the showing the TCE concentration trend in monitoring well DMW-6 is provided in Appendix B. - 8 hart hickman SAAAA-blaster Projects`NC DOT-DOTIDOT-500s ContractlDOT-504 Statesville 661May 2015 ReportUSemi-Ammel GWM Report.doc SMARTER ENVIRONMENTAL SOLUTIONS 4.0 Evaluation of Natural Attenuation Parameters Natural attenuation of groundwater contaminants occurs by physical, chemical, and biological processes. Biodegradation by reductive dechlorination is a primary degradation pathway for the type of constituents present at the site. Additional data on reductive dechlorination including indicator parameter data and daughter product concentrations are discussed below. The target potential DOT compounds at the site are amenable to natural attenuation. 1,1,1-TCA and TCE predominantly biodegrade under anaerobic conditions by a process known as reductive dechlorination. 1,1,1-TCA also degrades abiotically to 1,1-DCE. Historically, there was some evidence of natural degradation of these compounds based on the presence of potential daughter products: 1,1-DCE, l,l-DCA, and cis-1,2-DCE. However, natural site conditions were not highly favorable for reductive dechlorination. The EOSO injection was designed to enhance conditions for biodegradation of the constituents of concern, and general favorable results in concentrations trends are being observed since the injection of EOS® in December 2012. Recent and historical biodegradation data are presented in Table 7. A discussion of the recent indicator parameter data from February 2015 is provided below. 4.1 Competing Electron Acceptors Various electron acceptors can potentially compete with reductive dechlorination, including DO, nitrate, sulfate, iron (III), and carbon dioxide (methanogenesis). Each sequential reaction reduces the ORP of the groundwater into the range within which anaerobic reductive dechlorination can occur most efficiently. These parameters or their byproducts (e.g., Fe(11) and methane) were measured to assess the prevailing redox conditions at the site. A brief discussion of each parameter is provided below. 9 hart ► hickman SAAAA-Master Projects NC DOT-DOTIDOT-500s ContradOOT-504 Statesville 661May 2015 ReportVSewma i-Aml GWbi Report.doc SMARTER ENVIRONMENTAL SOttPflOPiS Dissolved Oxygen DO is used by microbes as an electron acceptor for the biodegradation of organic carbon. Reductive dechlorination occurs under anaerobic or low DO conditions. DO concentrations close to or less than 1 mg/l are favorable. Dissolved oxygen measurements ranged from 0.97 mg/l (DMW-1) to 3.51 mg/1 (DMW-8) in February 2015. Monitoring wells with dissolved oxygen levels close to or less than 1.0 mg/1 included monitoring wells DMW-1, DMW-2, and DMW-6. The measured dissolved oxygen concentrations in most impacted monitoring wells indicate conditions conducive for reductive dechlorination to occur. Nitrate/Nitrite Nitrate may be used as an electron acceptor for anaerobic biodegradation via denitrification. In this process, nitrate is reduced and nitrite is produced. In general, nitrate concentrations in the plume less than background are considered indicative of anaerobic biodegradation. At concentrations greater than 1 mg/l, nitrate may compete with the reductive dechlorination process. Nitrate was detected at concentrations which ranged from <0.020 mg/l (DMW-6, DMW-10 and DMW-11) to 2.70 mg/1 (DMW-2) in February 2015. These data suggest that nitrate reduction may be occurring in the plume, indicating the presence of anaerobic conditions favorable for reductive dechlorination. Most nitrate levels were less than 1 mg/l, and the potential for significant competition with reductive dechlorination is low. Sulfate/Sulfide Sulfate also may be used as an electron acceptor for anaerobic biodegradation. This process is known as sulfate reduction and results in the depletion of sulfate and production of sulfide in the aquifer. Sulfate concentrations within the plume below background concentrations and sulfide concentrations within the plume above background concentrations are indicative of anaerobic 10 S:UAA-T-faster Projects'NC DOT-DOTIDOT-500s Contrace-DOT-504 Statesville 66\May 2015 RepoRlSemi-Amwl GWM Report.doc hart hickman SMARTER ENVIRONMENTAL SOLUTIONS degradation by sulfate reduction. In addition, sulfate at concentrations greater than 20 mg/1 may compete with reductive dechlorination processes. Sulfate was detected at concentrations that ranged from 4.3 mg/l (DMW-1) to 118 mg/l (DMW- 7) in February 2015. Sulfate concentrations in the plume wells were generally greater than the concentration (<20 mg/1) considered most favorable for reductive dechlorination. In general, sulfate concentrations in the plume wells appear to indicate the potential for competition with reductive dechlorination. Sulfide was detected at concentrations which ranged from <0.10 mg/1 (DMW-1, DMW-2, DMW-3, DMW-6, DMW-9, and DMW-7) to 0.25 mg/1 (DMW-2) in February 2015. The low levels of sulfide concentrations in the plume wells appear to indicate that sulfate reduction is not significant anaerobic process at the site. Iron Iron reduction is an anaerobic process in which Fe" is reduced to Fe". The reduced form of iron is soluble. The presence of ferrous iron in groundwater greater than 1.0 mg/l is typically considered an indication of iron -reducing conditions. In February 2015, ferrous iron was generally not detected (<0.2 mg/1), other than 2 mg/l in DMW-10 and 8.5 mg/l in 'MW-11. Therefore, iron reduction appears to be occurring in some portions of the groundwater plume. Methane The presence of methane above background conditions indicates microbial degradation (methanogenesis) is occurring and strongly reducing conditions have been established. The fastest rates of anaerobic dechlorination typically occur under methanogenic conditions. Methane was detected at concentrations which ranged from <6.6 µg/l (DMW-2, DMW-7, and DMW-8) to 4,560 µg/l (DMW-11) in February 2015. These results indicate that strongly reducing conditions are present in portions of the plume. &NAAA-:faster Projects`\C DOT-DOTDOT-500s Contrac0DOT-504 Statesville GG\May 2015 Report\Senti-Amoral OWN1 Report.doc hart hickman SMARTER ENVIRONMENTAL SOLUTIONS 4.2 Geochemical Indicator Parameters Parameters that are indicators of conditions favorable for anaerobic biodegradation of chlorinated solvents include ORP, pH, and temperature. Ethene/ethane (end products) can also serve as indicators of complete reductive dechlorination. At the request of DENR, site wells also were sampled for eight RCRA (metals arsenic, barium, cadmium, chromium, lead, selenium, silver, and mercury). A summary of these data and recent previous natural attenuation indicator and target COC data are provided in Table 7. These parameters (February 2015 data) were evaluated to assess biodegradation processes at the site, and the results are discussed below. Redox Conditions QRP) The ORP of groundwater is a measure of electron activity and is an indicator of "the relative tendency of a solution to accept or transfer electrons. ORP of a groundwater system affects biodegradation rates. Reductive dechlorination is most efficient in the ORP range corresponding to sulfate reduction and methanogenesis (<-100 mV), but reductive dechlorination also occurs in the ORP range associated with nitrate, manganese, and iron reduction (-50 mV to 740 mV). ORP ranged from -32 mV (DMW-11) to 225 mV (DMW-1) in February 2015. ORP data are generally lower in impacted wells and are within the range in which reductive dechlorination may occur. PH and Temperature Groundwater pH values ranging from six to eight standard units are generally preferable for anaerobic biodegradation. The pH of groundwater affects the presence and activity of microbial populations. Acid generated during reductive dechlorination can decrease pH levels after a bioenhancement injection. Groundwater pH ranged from 5.79 to 11.72 in February 2015. The site pH values are within or close to the range, which is considered favorable for reductive dechlorination. 12 hart hickman S:tAAA-Master Proj"&NC DOT-DOT\DOT-500s Coutrace-DOT-504 Statesville 6GWay 2015 Report%ervi :Amual G% 1 Report.doc SMARTER EWRONMENTAL SOLUTIONS Temperature does notgreatly influence reductive dechlorination, but temperatures greater than n 20°C may accelerate biochemical processes. In February 2015, temperatures ranged from 12YC to 18.4°C. The average groundwater temperature for the site is approximately 14.4°C. These temperatures are in the range, which is considered satisfactory for biodegradation. Ethene and Ethane The dissolved gases ethene and ethane are non -toxic end products of reductive dechlorination of chlorinated solvents. Apart from ethane in DMW-6, DMW-10, and DMW-11, dissolved ethene and ethane were not detected in the site wells in the pre -injection or post -injection monitoring events. Ethane was detected in DMW-11 during pre -injection sampling in February 2012 and post -injection sampling in February and April 2013. Additionally, ethane was detected in DMW- 6 during the post -injection sampling in October 2013, January 2014, and February 2015, and in DMW-10 in February 2015. These results indicate that reductive dechlorination may be occurring in the vicinity of DMW-6, DMW-10, and DMW-11. Because ethene and ethane are highly volatile, it is not usual that these compounds were not detected in the remaining plume groundwater samples even if they may have been present in groundwater at low levels. RCRA Metals In February 2015, the RCRA metals barium, cadmium, chromium, and lead were detected in select site wells above pre -injection metals concentrations detected in December 2012. At the request of H&H, the metal concentrations were subsequently confirmed by the analytical laboratory. The RCRA metal concentration increases may be associated with elevated turbidities noted in the monitoring wells. Additionally, because RCRA metal concentration increases were also noted in monitoring wells located greater than 100 ft upgradient of the injection area, the increases do not appear to be related to the 2012 bioenhancement injection. RCRA metals will continue to be evaluated during future sampling events. 13 &NAAA-(Master ProjecteNC DOT-DOT\DOT-500s CgatracPDOT-504 Statesville 66\May 2015 Report\Semi .Aim=l G\VM Report.doc hart 01 hickman SMARTER ENVIRONMENTAL SOWTIONS 4.3 Electron Donor TOC TOC is utilized as an electron donor in the reductive dechlorination process and, therefore, is needed to drive the process. Organic carbon can be either naturally occurring or introduced artificially. The goal of the EOS injection was to provide a carbon source to drive the reductive dechlorination process. The presence of TOC at concentrations greater than 20 mg/L is considered ideal for biodegradation of chlorinated solvents. In February 2015, TOC levels ranged from 3.2 mg/l (DMW-9) to 20.9 mg/1(DMW-11). The TOC levels near the injection area appear to have been enhanced by the injection. H&H will continue to will monitor for the presence of TOC in other portions of the plume during future monitoring events. Metabolic Acids In groundwater, fermentation of EOS produces metabolic acids including lactic, pyruvic, acetic, propionic, and butyric acids. The production of these acids releases hydrogen into groundwater, which is then utilized by indigenous microbes in reductive dechlorination. In January 2014, groundwater samples were analyzed for metabolic acids to evaluate the presence of EOS breakdown products. The metabolic acid results are summarized in Tables 8. Metabolic acids were generally not detected in plume wells in January 2014. In accordance with the UIC monitoring plan, the first year of post -injection sampling has been completed; therefore, metabolic acids are no longer monitored. 4.4 Presence of Degradation Daughter Products Degradation or daughter products have been detected in site groundwater. The presence of the 1,1,1-TCA daughter product 1,1-DCA and TCE daughter product cis-1,2-dicholoroethene (cis- 1,2-DCE) provide direct evidence that biodegradation by reductive dechlorination of the parent VOCs has occurred. In general, daughter product concentrations continue to be present in higher 14 hart hickman SAAAA-Master Projects`NC DOT-DOT\DOT-500s ContracV.DOT-504 Staten Ue 66\May 2015 Report4Semi-AmwI GNVbi Report.doc SMARTER ENVIRONMENTAL SOWNONS concentrations relative to parent products. The continued presence of these daughter products indicates that reductive dechlorination is occurring. In addition to reductive dechlorination, 1,1,1-TCA also undergoes significant degradation by abiotic processes in which it is transformed to 1,1-DCE or acetate in the presence of water. The presence of significant 1,1-DCE concentrations compared to TCA in well DMW-6 indicates that abiotic degradation of TCA is also occurring in the plume area. 15 hart hickman SAAAA-'Master Projects�NC DOT-DOTIDOT-500s ContracttDOT-504 Statesville 66\May 2015 RepoitSemi-Annual GNVM Report.doc SMARTER EWRONMENTAt. SOUMONS 5.0 Summary and Conclusions H&H has implemented an enhanced bioremediation remedy and completed the pre -injection baseline and quarterly post -injection performance monitoring events at the former Asphalt Testing Laboratory Site No. 2-66 in Statesville, NC. The purpose of the remedial action was to address chlorinated solvents in groundwater. The pre -injection baseline monitoring event was completed in February/December 2012 and post -injection performance monitoring events are being conducted. The following summarizes the results of the sampling events and performance of the bioenhancement injection activities: 0 Groundwater impacts, including TCE, l,l,l-TCA, and their daughter products, are present near and downgradient of the former asphalt testing laboratory. Groundwater impacts exceed groundwater standards in two deeper saprolite monitoring wells. No impacts above standards were detected in bedrock monitoring wells. • No ground water impacts were detected in monitoring well DMW-8 located on the opposite side of the unnamed tributary of Third Creek from the former asphalt -testing laboratory. The absence of ground water impacts in DMW-8 indicates that the tributary is acting as an effective hydraulic barrier. 0 Target compounds were not detected in the active, upgradient on -site water supply well or in the unnamed tributary of Third Creek in February 2015 or June 2015, respectively. • A bioenhancement agent (EOS®) was injected into 36 injection wells in December 2012. Post -injection data collected most recently in February 2015 indicate that TCE concentrations are decreasing in plume wells DMW-6, DMW-9, and DMW-11. These trends indicate that the EOS' injection has resulted in enhanced bioremediation within portions of the groundwater plume area. Concentration trends will continue to be evaluated during future sampling events. 16 hart ► hickman S:1AAA-Duster ProjectA C DOT-DOTIDOT-500s Contract'DOT-503 StatenUe 66Way 2015 ReportLSenri-Annual GNDf Report.doc SMARTER ENVIRONMENTAL SOLUTIONS In accordance with the UIC permit, H&H has completed two years of post -injection quarterly performance monitoring. The EOS® injection has been effective at reducing groundwater parent COC concentrations and continued reduction in parent COCs is expected in the future. As a result, H&H is reducing the ground water monitoring schedule from quarterly to semi-annually. The next ground water monitoring event will be conducted in August 2015 with a monitoring report submitted to DOT in Fall 2015. During the sampling event, groundwater samples will be collected from deeper saprolite monitoring wells DMW-1, DMW-2, DMW-6, DMW-8, DMW-9, DMW-10, and DMW-11; and bedrock monitoring wells DMW-3, DMW-4, and DMW-7. Groundwater samples will be submitted to a North Carolina certified laboratory for analysis of VOCs by EPA Method 6200B, reporting only the EPA Method 601 halogenated VOC list and RCRA metals. Due to the extensive amount of natural attenuation data collected during the post - injection quarterly performance monitoring, natural attenuation parameter sampling will be reduced to select measurements including TOC, DO, pH, ORP, and temperature. H&H also will collect a groundwater sample from the active on -site water supply well WSW-4 and the creek located on the northern portion of the site during the August 2015 sampling event. The water supply well will be purged for approximately 15 minutes prior to sample collection. The samples will also be analyzed for EPA Method 601 halogenated VOCs by EPA Method 6200B. 17, SAAAA-Mfaster Projects\NC DOT-DOMOT-500s Contract\DOT-504 Statesville WAlay 2015 Report%enu-Avoail GWbi Report.doc hart hickman SMARTER ENVIRONMENTAL SOLUTIONS Table 1 Water Supply Well Inventory Former ATL Site No. 2-66 Statesville, North Carolina H&H Job No. DOT-504 Map ID Well Owner & Address Well Status Distance and Direction from Former Asphalt Testing Laboratory WSW-1 Maymead, Inc., 164 Bostian Bridge Drive, Statesville Abandoned On -site, near former asphalt laboratory WSW-2 Maymead, Inc., 164 Bostian Bridge Drive, Statesville Abandoned On -site, near former asphalt laboratory WSW-3 Dorothy Davis, 124 Bostian Bridge Drive, Statesville Active --1,200 ft, cross -gradient WSW-4 Maymead, Inc., 164 Bostian Bridge Drive, Statesville Active On -site, —500 ft, upgradient WSW-4A Maymead, Inc., 164 Bostian Bridge Drive, Statesville Inactive On -site, —500 ft, upgradient WSW-5 Lance & Melissa Lingle, 913 Buffalo Shoals Road, Statesville Active —650 ft, cross -gradient WSW-6 Fred Davis, Buffalo Shoals Road, Statesville Active —800 ft, upgradient WSW-7 Fred Davis Estate, Buffalo Shoals Road, Statesville Active —1,000 ft, upgradient WSW-8 Dorothy Davis, 868 Buffalo Shoals Road, Statesville Active —1,100 ft, upgradient WSW-9 Dorothy Davis, 868 Buffalo Shoals Road, Statesville Active —1,100 ft, upgradient WSW-10 Jerry Hinson, 917 Buffalo Shoals Road, Statesville Active —900 ft, upgradient WSW-11 Jack & Betty Wooten, 897 Buffalo Shoals Road, Statesville Active —1,000 ft, upgradient WSWA2 Margaret Cloer, 881 Buffalo Shoals Road, Statesville Active —1,200 ft, upgradient WSW-13 Jack & Betty Wooten, 871 Buffalo Shoals Road, Statesville Active —1,200 ft, upgradient WSW-14 Jack & Betty Wooten, 865 Buffalo Shoals Road, Statesville Active —1,400 ft upgradient WSW-15 Jerry Hinson, 911 Buffalo Shoals Road, Statesville Active —900 ft, upgradient WSW-16 Wooten Family of NC, 847 Buffalo Shoals Road, Statesville Active —1,200 ft, upgradient WSW-17 Garland Cloer, 889 Buffalo Shoals Road, Statesville Active —1,200 ft, upgradient Notes: Owner and address information based on Iredell County GIS Database and recent H&H windshield survey.
